JOIN'IING-TOOL.

To all whom it may concern:

Be it known that 1, JOHN WV. WVRIGHT, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Jointing-Tools, of which the following is a specification.

This invention relates to new and useful improvements in jointing tools for use for bricklayers, and has for its object to provide a tool of such class, in a manner as iereinafter set forth, embodying adjustable and combined means for striking and finishing the various joints required in the laying of bricks.

Further objects of the invention are to provide a tool for the purpose set forth and in a manner as hereinafter referred to, which is simple inits construction and arrangement, strong durable eflicient and convenient in its use, and comparatively inexpensive to manufacture.

To the accomplishment of these and such other objects as may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes in the form, proportions and minor details of construction may be resorted to, without departing from the principle or sacrificing any of the'advantages of the invention, which come within the scope of the claims hereunto appended.

- In the drawing wherein like reference characters denote corresponding parts throughout. the several views Figure 1, is a side elevation of a jointing. tool in accordance with this invention.

Fig. 2, is a plan.

Fig. 3, is a longitudinal sectional view.

Fig. 4, is a perspective view of the raking blade.

Fig. 5, is a detail of the raking blade.

Fig. 6, is a sectional detail illustrating a modified form of clamping member for the raking blade.

Referring to the drawings in detail, there is shown a jointing tool for brick construction work, comprising an elongated fiat handle 1, having extending from its forward end a guide member 2, for a raking blade to be hereinafter referred to. The

Specification of Letters Patent.

Patented Sept. 28, 1920. 1920. Serial No. 389,852.

member 2, at its forward end is provided with a pair of longitudinally extending and depending guide flanges 3, one of which is arranged at each end of the member 2, and between said flanges 3 is positioned the, raklng blade. The member 2, intermediate its ends is bent at right angles to form a shoulder 4, which abuts against the forward edge of the handle 1, and the member 2 is then bent so as to be arranged against one face of the handle 1. The member 2, is fixedly secured to the handle 1, as at 5.

Formed integral with and extending at right angles with respect to the handle 1, is a supporting cross-arm 7, which carries a pair of finishing bars 8 and 9, integral therewith at the respective ends thereof. The bars 8 and 9 are disposed at an angle with respect to the arm 7, extend forwardly therefrom and are inclined toward each other and toward the guide member and raking blade.

The thickness of the finishing bar 8 is considerably greater than that of the bar 9, and this variation is provided to permit and facilitate the finishing operation of various widths of joints. The forward and rear ends 10 and 11, respectively of the bars 8 and 9, are rounded off for the purpose of facilitating the movement of the bars through the joint, which movement is always in the forward direction during the finishing operation.

A raking blade 12, formed with a longitudinally extending elongated slit 18, is positioned intermediate the bars 8 and 9, and against the guide member 2. The blade 12 is slidably mounted for adjustment against the guide member-2 and is maintained in adjusted position through the medium of a clamping member to be presently referred to;

The forward end of the blade 12, extends beyond the ends 10 of the bars 8 and 9, and is shaped to form a pair of raking bits 17 and 18, each of a different width and length relatively to each other. The different widths provide for use in connection with different size joints, and the setting up of one bit of greater length than the other enables the operation of one bit without interference from the other.

The extreme forward ends 19 and 20 of the bits 17 and 18, are bent upwardly at right angles with respect to the blade 12, to a distance commensurate to the thickness of ing bits, and which willprevent the throw ing away of the blade when the bits become worn. The blade can be adjusted the desired distance so that a new pair of bits can be formed on the end thereof.

The clamping member, which is positioned against one face of the guide member, consists of a body portion 23, secured. v at its forward end, as at 24:, to the guide member 2, and projecting rearwardly from the body portion 23, as well as being offset with respect thereto, is an extension 25, which has its rear portion extended onto the rear of the guide member 2; The extension 25, intermediate its ends is formed with an opening 26, in which is secured an interiorally threaded sleeve or collar 29. The open ing 26, alines with an opening 27 formed in the guide member 2. The body portion 23,'at each side thereof is formed with a depending clamping aw 28, which overlaps a flange 3 and engages the raking blade 12. Adjustably mounted in the collar 29 and extendingthrough the opening 27 is a clamping screw 30 having a pointed end which engages the blade 12, whereby when'the screw '30 is adjusted'toward the blade12, the engagement of the point thereof against the blade will set up a clamping action between the jaws 28 andthe blade 12 so *that'the latter will "be prevented from shifting'durin .the operation of one of the raking bits.

he forward end of the body'portion 23, of the clamping member has extending thereon an angular shaped bracket 31, which supports a shaft 32, for a guide wheel 33, the latter rotatably mounted 011 the shaft 32. The. wheel 33 is provided to facilitate and guide the tool during the use thereof.

Referring to the modified form shown in Fig. 6,'which illustrates a modificationof the clamping member for the raking blade,

pending jaws 35. The member or rather the body portion 34 is secured to the guide member 39, as at 36, the latter is in the form 'of a rivet which extends above the body portion 34, and which forms a pivot for a rearwardly extending clamping spring 37, the latter is disposed at an inclination and bears against the rivet 38, for securing the guide member 39, to the handle 40. The

spring is moved to seat on the rivet 38, a

binding action is setup-between the jaws 35 and the blade 43, which holds the latter in osition. r e That I claim is 1- r 1. A' jointing tool for bricklayers comprising a handle, an inclined finishing bar supported by and projecting toward the plane of said handle, an adjustable raking blade having a bit, means for clamping the blade with the handle, and a guide wheel supported from'said means.

2. A jointing tool for bricklayers comprising a handle, a pair o-ffinishing bars supported from the'handle and inclining in opposite directions toward theiplane of the handle, a raking blade extended-between the finishing barsand provided with a longitudinal slit and further having apair of raking "bits, means for adjustably clamping saidblade with the handle, and a guide "wheel supported from said means.

A jointing tool for bricklayersycom prising a handle having a guide member projecting forwardly therefrom, inclined -finishing bars carried by the handle,aslitted raking blade positioned against said member, said blade having a pair of raking bits,

a clamping member secured to the guide member and associated with said blade for ad ustably clamping it in position, and a guide wheel supported from the clamping member.

34 denotes the body portion of the-clamping member and which is provided with'the de- In testimony whereof I afiix my si nature.
